SAP MTA Deployment Descriptor

What is the purpose of the SAP MTA deployment descriptor? So we will tackle the following information about the MTA deployment descriptor from SAP.

What Is SAP MTA Deployment Descriptor?

The SAP MTA deployment descriptor is a text file used to configure the Internet Information Server (IIS). It is concerning the SAP NetWeaver installation.

It contains the IIS configuration settings for the SAP NetWeaver Web application server. The deployment descriptor is an optional file that resides in the path specified by its location attribute.

That is usually the installation directory from SAP MTA and config. It has to be present for the Web application server to start. 

The deployment descriptor must be named web_server.xml. It does not affect the operation of the SAP NetWeaver Application Server. 

Instead, it configures IIS to support one or more Web applications that are deployed on the Web application server. Also, independent of whether they are deployed on the same machine or additional machines.

How do Companies Benefits From Deploying This?

Companies can make their Web applications publicly available over the Internet. They can also make their Web applications available to other SAP NetWeaver Application Server deployments. 

As long as they have a trust relationship between them. Then it is possible to do so. With the deployment descriptor, companies can not only run their Web applications on AS ABAP and AS Java. 

It also gives them control over how IIS is configured to support the Web application server. The deployment descriptor is an XML file that contains the following information: 

The HTTP port of the Web application server The protocol (HTTP or HTTPS). That the Web application server uses to listen for requests from IIS. 

How SAP MTA Deployment Works?

The IIS accepts requests from the web browser and forwards them to AS Java or AS ABAP. It does this by using a protocol called SOAP over HTTP (or HTTPS). 

The Web application server creates a session to respond to the request. It is only kept alive as long as IIS is open and running. 

The Web application server uses the deployment descriptor to configure how the IIS will receive requests. 

How To Configure SAP MTA Deployment Descriptor?

To configure the deployment descriptor, you must have an understanding of XML. It is based on an XML schema. So you should have some experience with XML schema design. 

The deployment descriptor is created in conjunction with an XML schema that describes its structure. The schema defines all of the elements used in the document and their attributes. 

So the schema can be created programmatically or by hand. In addition, there are third-party XML editors that you can use to create and edit XML documents. 

You must ensure that the schema you use conforms to the XSD standard for XML schemas. Furthermore, there are advantages and disadvantages that we will discuss below.

Advantages Of SAP MTA Deployment Descriptor:

It is a highly configurable deployment descriptor for Web applications. It enables you to control how the IIS listens for requests from the Web application server. 

The deployment descriptor makes it possible to launch the Web application server without starting the IIS. This is a great advantage when the Web application server is not using an HTTP port that is already in use. 

The deployment descriptor allows you to specify the path of the Web server’s root directory. It also enables you to control access control lists (ACL) for the Web application server’s directory structure. 

Disadvantages Of SAP MTA Deployment Descriptor:

XML schema design can be difficult and time-consuming. So you should plan and spend time researching before designing your deployment descriptor.
